Automated room acoustic measurement

In the field of Auditory Augmented Reality (AAR), one goal is to offer a listening experience that comes as close as possible to a real scenario. Measured spatial room impulse responses (SRIRs) describe the acoustics of a room and can serve as a reference for acoustic simulations or parameterization of room acoustics. The research group is developing an autonomous system for measuring SRIRs using a mobile robot platform. The system consists of a commercially available self-propelled platform on which a microphone array is mounted, while the sound sources are distributed at fixed positions in the room. The system is capable of performing high spatial resolution measurements of SRIRs in a uniform grid or an arbitrary grid. Current research projects are investigating how acoustically relevant areas in a room can be automatically recognized in order to measure only relevant areas with high resolution. The interaction with spatial auditory perception in AAR applications is also part of current research.
